Reddit mentions of Batman: The World of the Dark Knight

If you liked that, you'll like this book I just picked up by DK/DC. Incredible book that goes through all the main storylines and has a bunch of graphics like that. For example:

I got it at my local bookstore, but I'll see if I can find the Amazon link for it! It's honestly a great encyclopedia on the batman mythos.

I don't particularly recommend any of these books, but you kept saying that word encyclopedia so, well, those three may interest you.
